install problems

[dicook]

Seems that a fortran library is needed for MacOS

install.packages("fable", repos = "https://tidyverts.org/")

Can you try to install from GitHub again? I've made some changes which may fix this issue.

remotes::install_github("tidyverts/fable")

I also have problems with installation.

install.packages("fable", repos = "https://tidyverts.org/")

ERROR: dependencies ‘fabletools’, ‘RcppArmadillo’ are not available for package ‘fable’

After installing the above two packages, I get

ld: warning: directory not found for option '-L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin15/6.1.0'
ld: warning: directory not found for option '-L/usr/local/gfortran/lib'
ld: library not found for -lgfortran
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Solved the issue by following this article. Had to download gfortran 8.2 from here and change the entry in Makevars accordingly (mine was FLIBS=-L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin18/8.2.0 -L/usr/local/gfortran/lib -lgfortran -lquadmath -lm).

I also used remotes::install_github("robjhyndman/fpp3-package") to install everything at once.

fable is now available on CRAN 🎉
Hopefully this resolves all installation issues.
